Product Description:
The 19.Z1.B04-1000 is a three-phase sine-wave EMC filter produced by KEB as part of the Z1 Sine Wave EMC Filters series. Installed between an inverter and its motor load, the unit shapes the pulse-width-modulated drive output into a smooth sinusoidal waveform, which lowers electromagnetic emissions and reduces motor insulation stress. By suppressing steep voltage edges and common-mode currents, it helps automation panels meet industrial noise limits while extending cable and bearing life in variable-speed conveyor, pump, and fan systems used in industrial machinery.
The filter is designed for a nominal line voltage of 3 × 400 VAC, and its windings can carry up to 94.5 A during short-term peaks while supporting a continuous current rating of 63 A. A core inductance of 467 µH provides the reactance needed to attenuate switching harmonics without introducing resonance with the motor’s leakage capacitance. Under full load, the additional impedance produces only a 4 % voltage drop, which remains acceptable for standard IEC motor tolerances. Internal copper paths exhibit 4.4 mΩ of DC resistance, so conduction losses remain modest during extended operation. The enclosure is classified as IP20, which indicates touch-safe terminals but still requires installation inside a ventilated control cabinet. The three input phases connect to screw lugs, and the PE stud bonds the filter core to equipment ground to drain common-mode noise from the inverter output.
For transient events, the insulation withstands up to 550 VAC, giving added headroom when drives operate on high DC bus configurations. Thermal rise is limited by a power dissipation of 142 W, and the unit can be used in ambient temperatures from -10 °C to 45 °C without derating. A mass of 10.3 kg must be supported on the panel backplate, and conductors up to 35.0 mm² fit into the terminal clamps for connection to heavy-gauge motor leads. The unit also uses an M6 PE connection, and its operating range supports use with servo systems and general-purpose induction motor drives where low waveform distortion is important.
